骨架大:最新測試指數證明"你真的不胖"大綱

If you're one of the legions of slim, fit and healthy people whose BMI (Body Mass Index) makes them ‘technically' overweight, this story will be music to your ears. A new test is about to launch - called the ABSI.

很多人BMI指數(身體質量指數)“超重”，實際上卻健康苗條。如果你也是其中的一員的話，那麼下面的這個新研究可能會讓你覺得很中聽。一種新的測試體重的指數誕生了。

BMI is calculated by dividing your weight (in kilograms) by your height (in metres) squared. It has been widely criticised for years.

BMI指數(身體質量指數)的測量方式是：體重(千克)/身高(釐米)的平方。而近年來，這一指數受到的非議頗多。

‘The BMI is flawed because it doesn't take into account where you carry fat or how muscular you are,' says Sue Baic, a dietician from Bristol University. ‘A woman with a fat stomach, thick waist and skinny arms and legs could be deemed a healthy weight - yet people who carry fat around their mid-section are more at risk of heart disease, diabetes and even certain cancers.'

來自布里斯托大學的營養學家Sue Baic表示，“BMI指數是有缺陷的，因爲它沒有辦法說明人體內有多少脂肪或多少肌肉。比方說，一名女性她肚子肥大卻四肢纖細，而她的BMI指數有可能顯示的就是健康。然而，腰腹部肥胖的人羣患心臟病、糖尿病和某些癌症的危險性更大。”

To calculate your ABSI you take your waist measurement (in centimetres) and divide that by the square root of your height (in centimetres) multiplied by the square of the cube-root of your BMI.

而新推出的ABSI指數是這麼計算得出的：腰圍(釐米)/[身高(釐米)的平方根乘以BMI的立方根的平方]。

‘It's a very complicated formula!' says Sue. ‘But an online calculator is in development. I think it's a brilliant measure of how healthy you are and it could end up replacing BMI.'

營養學家Sue表示，“這是一個很複雜的公式，但是網絡計算器發展得很快，可以幫你算出來。這是個天才的計算方式，能夠告訴你，你到底有多健康。以後它會代替BMI指數的。”
